In this paper, we investigate how European households changed the diversity of their financial portfolios in response to the Great Financial and the subsequent European Debt Crisis. For this purpose we apply a Difference-in-Differences (DiD) approach estimated as a correlated random effects (CRE) model to six waves of the Survey of Health, Ageing and Retirement in Europe (SHARE). We find that households ...
In this article, we provide the results of a simple quantitative analysis of the potential remedies to reduce the supply gap in Germany that arises if Russia stops delivering natural gas. We take into account the supply potential of other suppliers, and combine this with an analysis of the additional supply potential by stopping electricity generation from natural gas. Moreover, we investigate the ...
The use of green hydrogen can support the decarbonization of sectors which are difficult to electrify, such as industry or heavy transport. Yet, the wider power sector effects of providing green hydrogen are not well understood so far. We use an open-source electricity sector model to investigate potential power sector interactions of three alternative supply chains for green hydrogen in Germany in ...
More than 950,000 refugees from Ukraine have sought protection in Germany since the Russian invasion on February 24, 2022. The project “Refugees from Ukraine in Germany” is the first comprehensive, representative social science survey of this group.

More than a million refugees from Ukraine have sought protection in Germany since the Russian invasion on February 24, 2022. The project “Refugees from Ukraine in Germany” is creating the first representative database on these people, on the conditions that led them to flee, and on their integration into German society. Findings drawn from these data will lay the foundation for groundbreaking...
Cost of renewable energies have dropped, approaching wholesale power price levels. As a result, the role of renewable energy policy design is shifting – from covering incremental costs towards facilitating risk-hedging. An analytical model of the financing structure of renewable investment projects is developed to assess this effect und used to compare different policy design choices: contracts for ...
